Supplier: Merck
Description: RP-2, RP-8 and RP-18 are based on silica gel 60 modified with aliphatic hydrocarbons. The chain length, in combination with the degree of modification, defines the ability to tolerate water in the solvent system and strongly affects retention. Migration time increases in the order RP-2, RP-8 and RP-18 using the same solvent composition. RP-8 and RP-18 can be run with up to 60% water in the solvent system.
Supplier: Merck
Description: PLC (Preparative Layer Chromatography) plates are based on the same proven Merck silica-binder technology as analytical TLC plates. Plates are available with layers of unmodified silica gel or RP-18 modified silica gel in several layer thicknesses, ranging from 500 to 2000 µm, with or without fluorescent indicator.
Supplier: VWR Collection
Description: Modified silica layers are, depending on the modification, suitable for polar to unpolar eluents or eluent mixtures.

Supplier: Merck
Description: Our NH₂, CN- and DIOL-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.
Supplier: Merck
Description: TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.
Supplier: Merck
Description: HPTLC LiChrospher® plates are based on spherical-shaped silica 60 with a particle size of 7 µm, and narrow particle size distribution similar to the phases used in HPLC. LiChrospher® HPTLC plates possess a selectivity that is comparable to respective HPTLC plates, however, plate height and separation numbers are further improved resulting in shorter analysis times.
Supplier: Merck
Description: Coupling TLC plates to mass spectrometry is a new field of high interest, which will contribute strongly to the progress of planar chromatography. The MS-grade plates are much cleaner than standard TLC/HPTLC plates providing higher sensitivity and reduced background signals. This allows trace analysis with mass spectrometry detection in lower nanogram range.

Supplier: Thermo Fisher Scientific
Description: Silica gel C18-RP 17% C (∼0,7 mmol/g) Ø 48-65 µm
Supplier: Thermo Fisher Scientific
Description: CAS No.: 71889-02-6
Supplier: MACHEREY-NAGEL
Description: Octadecyl-modified HPTLC silica layers available as glass plates or ALUGRAM® aluminium sheets. Recommended for aminophenol, barbiturates, preservatives, nucleobases, polycyclic aromatic, hydrocarbons, steroids, tetracyclines, and plasticisers (phthalates).
Supplier: MACHEREY-NAGEL
Description: Octadecyl-modified HPTLC silica glass plates are recommended for alkaloids, amino acids, preservatives, optical brighteners, barbiturates, polycyclic aromatic hydrocarbons (PAH), drugs, peptides, flavonoids, phenols, indole derivatives and steroids.

Supplier: Avantor
Description: LiChrospher® is a silica available in both endcapped and non-endcapped C8 and C18 phases.

Supplier: Merck
Description: Monolithic silica technology: A new age in chromatography. Chromolith® columns are based on silica so existing methods can be easily transferred with only minimal investment in new method development work. 'Sol-Gel' technology allows highly porous monolithic rods of silica to be formed. These feature a bimodal pore structure provides a unique combination of macropores and mesopores.
